Title: Manufacture of flexible joint
Inventor: SUZUKI SHIGERU
IPC: B29C35/00
Filed: 1979-10-12
Abstract: PURPOSE: To enable the production of a flexible joint for a rocket motor which is excellent in softness and has a size accuracy, by a method wherein a given rubber component, consisting of an end hydroxyl group polybutadiene, diisocyanate, a trifunctional crosslinking agent, is used.  
     CONSTITUTION: In order to couple together a chamber 2 of a rocket motor 1 and a nozzle 9, a flexible joint 10, consisting of a plurality of metal rings 13 and a heat resisting rubber 14, is produced. The production of said flexible joint is such that, after a desired number of metal rings 21 are placed in a mold formed by molds 16, 17, 18, and 22, air in the mold is bleeded by means of a vaccum pump, and a given rubber component is poured through a plunger 26 for curing. The given rubber component used thereupon is a mixture of 1.8W2.1 of hydroxyl group number, an end hydroxyl polybutadien having 100W5,000 of an average molecular weight, disocynate, and trifunctional crosslinking agent, such as triole. This permits the miniaturization of an actuator because of a low modulus of shear elasticity.

Title: Intraosseous implant
Inventor: MURATA TAKESHI
IPC: A61C8/00
Filed: 1994-06-15
Abstract: PURPOSE:To provide a two-stage intraosseous implant constituted of an end collar section and a lower main body section, easily brought into contact and connection with a bone, suppressing bone absorption, and capable of suppressing infection and inflammation to the utmost by setting the maximum surface roughness of the collar section to a prescribed value. CONSTITUTION:In a two-stage intraosseous implant 1 constituted of an end collor section 1a and a lower main body section 1b, the maximum surface roughness of the collar section la is set to 3-10mum. Since bone cells prefer fine irregularities to a mirror finished surface, the affinity between the collar section 1a and a bone is increased when such irregularities are applied to the collar section 1a. As the maximum surface roughness is made smaller than 3mum, the affinity with the bone is decreased, and the resistance against bone absorption is remarkably decreased. As the maximum surface roughness is made larger than 10mum, the direct contact strength between the bone and the implant is increased, however plaque is easily stuck to the irregularities, bacteria in a mouth cavity are easily bred, and bone absorption easily occurs through infection and inflammation.

Title: Continuously manufacturing equipment of laminate
Inventor: ENDOU MUNEHIRO
IPC: B29K101/10
Filed: 1983-07-21
Abstract: PURPOSE:To produce a high grade laminate continuously by a simple construction, by a method in which high viscosity liquid is supplied to the back surface of a belt and is heated to high temperature by a heating device, and then the belt is heated to desired temperature under high pressure through this high temperature liquid. CONSTITUTION:Laminal stock papers 2 sent out from processed paper coils 1 impregnated with resin are preheated to the softening temperature of resin in a heating furnace 3, and then is inserted into between endless belts 10 made of metal. The opposite parts of these circulating belts are driven in the same direction by driving drums 11 and said belts pass through a high temperature pressurizing device 12, while synchronizing the belts with the base papers 2. Because the high temperature pressurizing device 12 applys high pressure to the base papers 2, the impregnating resin having been in fluid condition after preheating, penetrates fully into the fiber width of the processed papers. The resin is rapidly molded based on the thermosetting property of the resin, while heating the resin to higher temperature than preheated temperature by way of the metallic belts 10. After the laminate 4 has been completed, it is cured at the same temperature as the molded temperature in a high temperature heating furnace 13. After its finishing, the laminate is cut in size by a shearing machine 14 and is sent out onto a piler 16 by a conveying table 15 as a laminate sheet 5.

Abstract: PURPOSE:To evade the collision of packets at a binary switch and the concentration of the packet on the same output line by providing a binary switch group independent at every input line, and providing buffer memory between the output of the binary switch at final stage in each binary switch group and an output line. CONSTITUTION:The bits of destination addresses of the packets flowing in from the input lines 31, 32, 33, and 34 are checked when passing the binary switches 30 of independent binary switch groups 1-4, and they are routed based on a value '0' or '1', and are outputted from the binary switches 30 at final stage. In such a way, since the routing of the packets flowing in from the input lines 31-34 are performed in the independent binary switch groups 1-4, respectively, the collision of the packets can be evaded, and also, when plural packets flow out to the same without lines 51-54, output awaiting is performed by using the buffer memory 41-44, therefore, the collision of the packets at this part can also be evaded.

IPC: G06F11/34
Filed: 1987-05-30
Abstract: PURPOSE:To obtain reference for the performance improvement of a program (specially, a control program) by outputting not only the total number of instructions which re executed, but also the number of instructions executed in each specified measurement area (e.g., a program) by the kinds of the instructions to a list to be edited and outputted. CONSTITUTION:A program instruction execution frequency measuring instrument 2 analyzes instructions in a range between an address B1 reported from a branch instruction interrupting mechanism 30 and an address P0 stored in an after-branch address 51 at this time to adds analytic results (numbers of instructions by kinds) corresponding to the kinds of the instructions in an instruction execution frequency storage array 61. Then the program instruction execution frequency measuring instrument 2 stores an address P1 reported together with a address B1 in the after-branch address 51. An editing and output part outputs the measurement result list which is so edited that the total of executed instruction and the numbers of times of execution by the kinds of the instructions are obtained corresponding to respective measured programs according to the contents of an instruction execution frequency storage part.

Title: Control method of power unit
Inventor: KONOMA YASUO
IPC: F16H59/42
Filed: 1989-05-26
Abstract: PURPOSE:To ease the generation of shift shock by switching to high torque valve operating characteristic to start shifting during power-on and shift-up, when the power-on and shift-up are conducted during operation with low torque valve operating characteristic. CONSTITUTION:When the power-on and shift-down speed change of an automatic transmission AT during operation of an engine E with the variable valve timing mechanism VT of inlet and exhaust valves being made to low torque valve operating characteristic, a control unit CU switches the valve operating characteristic to high torque valve operating characteristic, and also starts shifting through a control valve CV. When the power-on and shift-down speed change is completed, the valve operating characteristic is returned to low torque valve operating characteristic. Hence, the reducing quantity of acceleration when the engine rotation is accelerated by receiving a driving force by the inertia on the transmission input side is minimized, and the generation of shift shock can be minimized.

Title: Light-emitting diode
Inventor: MURAKAMI TOMOKI
IPC: H01L33/14
Filed: 1984-06-28
Abstract: PURPOSE:To inhibit the generation of an edge-cross on the manufacture of an LED by thickening only a light-emitting region and thinning other regions in an active layer. CONSTITUTION:Only a light-emitting region is thickened and other regions are thinned in an active layer 3. That is, the layer 3 is formed onto a clad layer 2 with a recessed region, and shaped so that the thickest section of an active layer 3a on the recessed region extends over at least 1.5mum or more and an active layer 3b on sections except the recessed region is not more than 0.7mum thick. Since the area of the layer 3a is made extremely smaller than that of the layer at that time, an edge cross shaped on the growth of the layer 3 depends upon the thickness of the layer 3b. Consequently, since the thickness of the layer 3b is thinned, the edge cross generated on the growth of the layer 3 is reduced largely. In the layer 3a, on the other hand, the volume of the light-emitting region required for satisfying element characteristics is ensured by setting the depth of the recessed region of the layer 2 to a desired value.
